I would be interested in learning about this as well. If you find anything out could you possibly share it with the TRNSYS group? I have some experimental data for low concentration ratio CPCs which I'd like to model.<br>

Dear Shahrdad,There is more detail about these collectors in the classic text by Duffie and Beckman, which includes an example as well. Otherwise, you can try to contact the manufacturer and see if they have any insight.Best regards,Matt Duffy ----- Original Message -----From: "Shahrdad JavidRad" >;shahrdad@live.de<br>
